The Lilly Ledbetter Fair Pay Act of 2009 is a significant piece of legislation aimed at addressing wage discrimination based on gender by allowing individuals to file claims for pay discrimination within 180 days of their last discriminatory paycheck. This act extends the time frame in which employees can seek legal recourse, empowering workers to fight against pay disparities. It reflects the ongoing struggle for equal pay and represents a government response to social movements advocating for gender equality in the workplace.
